ABSTRACT:
An object-based bit rate control method and a system therefore provides a user with satisfactory quality of image by using significance of the object. The object is separated from the image, and significance is imposed on each object. A quantization parameter is differently varied according to the significance of the object. Especially, a variable width of the quantization parameter is controlled in a boundary region of the object and the other regions.
